@Jinxit not sure for powering, because I am using a Pixracer, but usb communication is not advised. At QGC control you have you have parameter CBRK_USB_CHK(PX4 stack) which will enable usb communication, but it is on your own risk. You should rather have UART-UART communication.

Also, i'm currently testing the Eagle Tree Airspeed MicroSensor V3, after calibration it calculates a SENS_DPRES_OFF of around 1500. From other logs i have seen the regular airspeed sensors range between 20-100 on this. The registered airspeed is MUCH lower then the actual speed (it registers 15m/s when it's actually flying around 22m/s). Anyone have any experience with that?

@dogmaphobic@DavidIngraham I'm using 12 gauge wire on the batteries and 13 gauge wire on the power module (just the standard that it comes with). The total wire length from the start of the battery to the power module sensor is about 7 inches. The wires don't get warm either. I also swapped the cable going from the power module to the Pixhawk and noticed no change in behavior. I changed the scale so that it reads the proper voltage at hover throttle but that just reverses the problem (I get higher voltage at idle). What do you think it might be?

Hii just got my px4flow and im not getting any Sonar outputim connected via i2c and both the distance and the integrated distance keep beeing zero.the sonar is active, i can hear a silent buzzing from it.i got a chinese one since the usual one is nowhere in stock

groundcontrol shows the same thing, firmware is the newest stable onesolderbridge is connected to 5V
